Thinking Machines Tinker

Thinking Machines Tinker is a flexible API platform designed for researchers and developers to fine-tune open-source language models using LoRA (Low-Rank Adaptation). Tinker abstracts away the complexity of training infrastructure, managing distributed GPU resources so users can focus on models, data, and algorithms. It supports a wide range of large foundational models and exposes powerful but simple primitives for customizing model training, sampling, and state management. The platform is well-suited for ML research teams who want efficient, scalable, and controlled model customization.
